I planted two identical dahlia tubers a couple of months ago. The shoots popped up around the same time and have been grown to the same size so far. They were planted in pots.
However, one of them seems to have gone a bit soft over the last week and is a slightly less vibrant green. It's not quite drooping or properly wilting yet but the leaves are soft in my fingers whereas the other one is stiffer. The stems are also more soft and bendy compared to the other one.
Any idea why one of them is going soft? Both pots are next to each other so get the same sun and rain. I first thought it may be down to a lack of water because the healthy dahlia is in a deeper pot (despite the soil feeling damp enough when I stuck my finger right into it) but since then it's been raining a lot over the last week, so they're definitely not thirsty.
It doesn't look like it's dying - yet, but I'm worried the wilting will continue to get worse until I lose it.
